I'm on episode 37
Does he actually get good?
He does in the manga but I think the anime is different.
Why did the manga end seem so rushed?
Not Rukawa good but a effective part of the team.
I don't think I'll be able to finish this show if nothing changes
Because he wanted to focus on his two actually good mangas, Vagabond and REAL.
he becomes rimfire
How else would you end it anyway? A ridiculous under-18 world basketball championship where team Japan plays USA to a draw a la ES21?
I only made it to episode 3, good on you OP. Slam Dunk is a poor mans Hajime.
